Title: Perpendicular circuit
Inventor: KAWAMOTO TETSUO
IPC: H04N3/16
Filed: 1987-09-18
Abstract: PURPOSE:To suppress fluctuation in perpendicular amplitude on a cathode-ray tube by utilizing a voltage in which a pulse from winding coupled closely with the high voltage winding of a flyback transformer is rectified as a source voltage in a sawtooth wave generation circuit. CONSTITUTION:The pulse from the winding coupled closed with the high voltage winding of the flyback transformer is rectified by a capacitor C2 via a diode D1 when a transistor Q1 is turned OFF, and the voltage is voltage-divided by a resistor R2 and a perpendicular ampltiude control variable resistor R3, and after passing a resistor R1, a charging current is supplied to the capacitor C1. Afterwards, the transistor Q1 is turned ON by applying a vertical synchronizing signal, and the charge of the capacitor C1 is discharged through a resistor R4 and the transistor Q1. And charging on the capacitor C1 is repeated again. In such a way, amplitude control is applied on a sawtooth wave, thereby, the stability of the perpendicular amplitude on the cathode-ray tube can be improved remarkably.

Title: Device for removing static electricity and preventing electrification
Inventor: KIKUKAWA KATSUTOSHI
IPC: H05F3/00
Filed: 1987-09-21
Abstract: PURPOSE:To remove static electricity and preventing electrification by adopting crystalline liquid and ceramic responsive to an arbitral voltage sharply. CONSTITUTION:Existing crystalline responsive to voltage sharply is formed with an electrode attached thereto by an conventional method, whereby a device is obtained. This device is installed on a TV screen, and when a TV set is put ON, static electricity charged on the screen is absorbed by this device, and thereby voltage is disappeared. Even if residual voltage is measured after the operation, the residual voltage can not be observed. This means that static electricity is removed. At the portion where this device is not attached, on the other hand, residual voltage the same as the initial case is observed. Since static electricity is eliminated by means of crystalline liquid, the removal of static electricity can be done without earthing. It is thus possible to eliminate static electricity on the screen of TV set by always providing this device on the TV screen.
